99 Grand Am Cyclinder Misfire Code

My 99 Grand Am has a misfire in cyclinder 5 fault code. We've changed plugs, wires, ignition coil and had the fuel injectors cleaned. She's definitely running smoother but we've still got the code. Anyone have ideas of what to do next? I'm on a crunch time table because my vehicle inspection is due now!

I would use a noid lite or have that cylinder's injector tested to make sure its getting pulsed.
